Note the lack of a pinhole for the iSight LED, as in the previous model. The LED is still in the same spot, and there is a circular pattern of micro-holes allowing light through. The holes weren't evenly drilled on our machine, letting more light through on the left side than the right. We didn't have a good enough lens to capture the effect.

The optical drive is now a 6X, dual-layer, 9.7mm SuperDrive (DVD-R DL/DVD-RW/CD-RW). The drive itself says UJ-857C, while System Profiler reports it as a UJ-857D. We can't explain the discrepancy.

The logic board layout is virtually identical to the previous model. Apple introduced a new cable connector that is soldered to the logic board better. This may reduce some of the problems we've had with the previous brittle connectors.

Here's the new Airport board. The world's worst kept secret is that this is actually an 802.11n draft chipset. We're not aware of any way to get the n-functionality in OS X yet, but some have been successful in Boot Camp with drivers for the D-Link DWA-645.

Note the three antenna cables coming into the Airport board. The previous model only had two cables. The additional antenna could provide better reception, or different frequencies (802.11n uses both 2.4 GHz and 5 GHz) for the new wireless chipset.
